HOW: I used a circuit board for an OEM heart rate monitor designed to be integrated with exercise equipment. When a user makes hand contact with the conductive metal attached to the circuit board, the electrical impulse of their heart muscle contraction is detected and amplified by the circuit board, and a digital 5V square pulse is sent to our PIC microchip. The PIC chip in turn sends a series of MIDI commands to a MIDI-controlled light board, which powers the lamp bulbs.
